पर्याय

• Only I and II follow

• Only I, II & IV follow

• Only II and III follow

• Either II or IV follow

Answer 1

Only I, II & IV follow
Conversion of statement (B) gives conclusion I. Hence conclusion I follows. Conclusion II is an implication of statement (C). Hence, conclusion II follows. Similarly, conclusion IV is the implication of statement (A). Hence, conclusion IV follows. Conclusion III does not follow from the statement (C).
